One time batch workflow to repair omission of data

One time batch workflow to repair omission of data

Hi,

I created a parent form (Product) and another form (Prices) that is used as subform in the parent form. In the parent form I have a field Category that must appear in the subform, but I forgot to create the field at first in the subform and now I have 100+ records created in that subform.

How do I write my batch workflow to tranfer the Category field to the subform ? Does it knows it has to do "for each record" since it is a batch workflow?

Please help !
